Here's some other options to try: 1. Repair LimeWire using the Add/Remove Programs utility
2. Right-clicking the Limewire icon and going to properties and changed compatability setting to Windows 2000.
3. If all these don't succeed, using your control panels, Remove LW & re-install it. You can get another copy by adding your email you registered with

So to reiterate: Update your Java, delete your LW Preferences folder, Use Repair from Control Panel, & if all those things don't fix it, Remove & Re-Install LW.
